1.Cleaning
In order to obtain high effective cleaning, ensure good work condition and production stability, high efficient vibration screen wasused in the process to separate big and small impurity. 
Suction type gravity stoner removing machine was applied to remove the shoulder stone and earth, and magnetic separation equipment without power and exhaust system were used to remove iron impurities. 
Dust removing wind net is installed.

2. Flaking
Flaking means a certainty granularity of soy lamella was prepared for flaked of about 0.3 mm, the oil of raw material can be extracted in the shortest time and maximum, and residual oil was less than 1%. sunflower oil making machine

3. Cooking
This process is heating and cooking for rapeseed which is easy to separate of oil and can provide the oil quantity from pre-press machine. It is easy to operate and have long life.

4. Oil press machine
The screw press machine is suitable to extract oil from oilseeds, such as sunflower seed, peanut, cottonseed, rapeseed etc.

These vegetable oil processing plants are equipped with big capacity, which mostly use in middle-large scale oil plant. They can be divided into two kinds: One is hot processing, which includes steam cooker and oil press. The steam cooker is used for oilseeds pretreatment before pressing. The other one is the cold processing. The advantage of this kind of machine is to press seeds at low temperature. It is about 80 degree, which can protect the nutrition element within the oil.

These oil plants feature with large capacity, high oil output, low oil residual, light processed fats color, good quality, rich nutrient.
These oil mill can process a number of oilseeds like peanut, soya, cotton seeds sunflower seeds, corn germ, rape seeds, canola, castor, sesame, neem seed, sheanut, palm kernel and the like. The most important equipment in the entire milling / pressing process is oil expellers which are used for high oil content seeds and also used for smaller capacity oil production plant.
